When an "install -d formula" fails, and the user gets dropped into an
interactive shell, set the HOMEBREW_DEBUG_INSTALL env var to the name
for the formula that failed. Also set variable if the user requests an
interactive install in the first place.
Note that this may be different than the formula being installed, since
it may have been a dep that failed.
Also remove todo in utils; users can now look for HOMEBREW_DEBUG_INSTALL
in their prompt command, and adjust their prompts accordingly.
If the user has, for instance, a non-system "xml2-config" in the path
ahead of the system and Homebrew folders, ./configure scripts which
look for and use this config script will get confused.
A formula using svn can now provide a spec:
:revisions => {...revision numbers...}
that contains a mapping of revision numbers to use
for externals.
The name of the external is keyed to the revision to
use for that external.
The symbol :trunk should be used to specify the reivsion
of the main repo.
An example from the Ffmpeg formula:
head 'svn://svn.ffmpeg.org/ffmpeg/trunk',
:revisions => { :trunk => 22916, 'libswscale' => 31045 }

Now makes use of `svn up` to make cache act like
a cache. Externals without a revision specified
are now checked out at HEAD, whereas before they
were ignored. Escaping arguments to backticks.
Making sure main repo is checked out before the
externals.

Report "Expected <supplied digest>, got <file's digest>"
when verify_download_integrity sees a mismatch. (It had
been, confusingly, reporting "Expected <file's digest>".)

If the user has linked the keg-only gettext, then a large number
of formulae which don't have "depends_on 'gettext'" will pick it
up anyway. Knowing this about the user's setup may help diagnose
bug reports.
Homebrew's pkg-config didn't originally add X11 to its search path.
This causes problems for long-time Homebrew users brewing software
that depends on X11-related packages, such as Cairo.
When a formula specifies both an `url` and a `head`, and the latter
specified a `:using` spec, brew would try to fetch the `url` using the
specified download strategy. With this change, brew respects `:using`
specs only when determining the download strategy for `head`.

A 'head' in a formula can now specify which download strategy to use via
a ':using' specification:
head 'http://svn.macosforge.org/repository/darwinbuild/trunk/',
:using => :svn
This reduces the number of cases where "download_strategy" needs to be
overriden.
